from ivtv-0.4.0/doc/video-quality.txt:

--- cut here ---

dnr_mode:
         0:  spatial and temporal noise removal filters
         1:  temporal only
         2:  spatial only
         3:  no noise filter

dnr_spatial:
         0..16:  0=no filtering  16=strongest filter
               (horizontal only, smoothing/lowpass)
dnr_temporal:
         0..16:  0=no filtering  16=strongest filter
               (inter-frame (time dimension), averaging)

--- cut here ---

so...

$ ivtvctl -c dnr_mode=3
$ ivtvctl -c dnr_spatial=0
$ ivtvctl -c dnr_temporal=0

The MPEG-2 settings I am curious about are:

framespergop
gop_closure
bframes
